Green Belt course

A Lean Six Sigma Green Belt is a professional who can independently lead improvement projects within their own department or function using the DMAIC methodology. Green Belts focus on reducing waste, improving quality, solving operational problems, and delivering measurable business results.

You can apply Green Belt skills immediately by identifying inefficiencies, analysing root causes, improving workflows, and using data to make better decisions. Many professionals start improving lead times, customer satisfaction, or process quality during the course itself.

This depends on your goals and what you intend to achieve. If you would prefer to employ Lean Six Sigma on a part-time basis, for example alongside other work, the Green Belt course would be the best choice. If it’s your aim to work with Continuous Improvement and Lean Six Sigma on a full-time basis, then the Black Belt course would be the right pick.

The full Green Belt certification journey typically takes between 2 and 6 months, depending on your training format and the duration of your practical improvement project.

Training and examination are often completed within a few weeks, while the project phase may take longer depending on your organisation and project scope. Certification requires both theoretical knowledge and successful practical application.

There are usually no strict entry requirements for Green Belt training. You do not need prior Lean Six Sigma experience, although having access to a real process improvement opportunity within your organisation is highly valuable for the practical project.

The cost of Lean Six Sigma Green Belt training at The Lean Six Sigma Company is £2,450 (+VAT). When comparing providers, it is important to look beyond the course fee and consider accreditation, ongoing support and project coaching, as well as international recognition.

Lean Six Sigma Green Belt courses are available throughout the UK in classroom, virtual instructor-led, and blended learning formats. This allows you to choose the study option that best fits your work schedule and learning style.

At The Lean Six Sigma Company, courses are offered regularly across the UK and online, with flexible scheduling and preparation through the MyTraining platform so you can combine study with your day-to-day responsibilities.

The Lean Six Sigma Company strives to organize its courses during normal working hours.

This is a conscious choice in order to avoid interfering with the private lives of our participants and to get them used to the idea of working with Lean Six Sigma during typical working hours, and continue this habit once they complete the course.

However, some local exceptions apply. Please reach out to to the helpdesk in your region if you have any questions

The best Lean Six Sigma course is one that combines practical application, recognised certification, and real business impact. A Green Belt course is often a strong choice for professionals who want to improve productivity, workflow efficiency, and operational performance.

Look for a programme based on ISO 18404 and ISO 13053 standards, with project coaching and a real improvement project requirement. This ensures the training goes beyond theory and delivers measurable results.

A Green Belt certification can strengthen both career progression and earning potential because it demonstrates practical problem-solving, leadership, and improvement capability. Employers value Green Belts because they can deliver measurable operational results rather than only theoretical knowledge.

In the UK, Green Belt certification is often recognised in roles related to operations, healthcare improvement, project management, supply chain, and continuous improvement. It can support promotion opportunities and increase visibility for leadership roles.

Yes. Lean Six Sigma Green Belt is highly relevant for Healthcare, Services, Finance, Government, Logistics, and many other sectors beyond manufacturing.

The methodology focuses on improving processes, reducing delays, increasing quality, and improving customer or patient outcomes. In Healthcare, for example, Green Belts often work on reducing waiting times, improving patient flow, or reducing administrative errors.

During your practical project, you receive guidance from an experienced Master Black Belt to help you apply Lean Six Sigma correctly and deliver measurable results. This includes support with project selection, defining scope, stakeholder management, and using the right tools throughout the DMAIC phases.

The goal is to help you create both learning value and measurable business impact.

The Lean Six Sigma Company stands out from many other UK providers because our focus goes beyond simply delivering Lean Six Sigma training. Our programmes are designed to ensure that delegates can successfully apply the methodology in practice and create measurable business results.

Our courses are highly interactive, using real-life case studies, practical exercises, simulations, and group discussions. In some cases, such as our Black Belt programmes, our courses are longer than comparable programmes, allowing for deeper learning and more hands-on practice.

A key difference is our ongoing support after the training. Delegates are guided by an experienced Master Black Belt throughout their practical improvement project, helping them apply the DMAIC methodology correctly and deliver measurable results.

Our certification is internationally recognised and aligned with ISO 18404 and ISO 13053 standards. We also hold ISO 21001 certification and work in partnership with the University of Bedfordshire, ensuring both strong academic quality and effective teaching methods.

All of our instructors have more than 25 years of practical experience and have worked as Master Black Belts, allowing them to provide real first-hand examples and practical guidance.

Finally, every delegate receives unlimited access to our online learning platform, MyTraining, which includes video lessons, e-learning modules, templates, tools, and an AI assistant for long-term support.

Yes, you do not need a strong statistics background to start Green Belt training.

The course teaches the analytical methods step by step and focuses on practical application rather than academic theory. The tools are explained in a business context, making them accessible for professionals from any industry or background.

DMAIC stands for Define, Measure, Analyse, Improve, and Control. It is the core Lean Six Sigma project structure used to solve process problems in a systematic and data-driven way.

During Green Belt training, you learn how to apply DMAIC from project selection through to sustainable implementation. By the end of the course, you will be able to use DMAIC to lead real improvement projects within your organisation.

After completing Green Belt training, many professionals continue leading improvement projects within their organisation and use their certification to support career progression into operational excellence, project leadership, or management roles.

For those leading larger cross-functional projects, the next development step is often Black Belt certification. This builds on Green Belt knowledge and focuses on more advanced analysis, strategic improvement, and coaching responsibilities.

Alternatively, those who want to create a culture of Continuous Improvement within their team and support team members in applying Lean tools themselves often choose Lean Leader training for further development.
